Reasons for creatinine to be below the standard value include malnutrition, low muscle mass, and severe systemic diseases.
Creatinine is a product of the body’s metabolism and comes from two sources, one endogenous such as the body’s own muscle breakdown and the other exogenous such as animal meat products. Therefore, patients with low creatinine may be due to too little animal food in their diet, or they may have muscle atrophy.
1. Malnutrition: It may be related to daily picky eating, resulting in too little intake of meat-based food, causing lower creatinine.
2. Too little muscle mass: such as thin body type, short size, elderly people, etc. All muscle mass is not high, may appear creatinine lower than normal value.
3. Serious systemic diseases: for example, anemia, hyperthyroidism, leukemia, tumors and other wasting diseases may be manifested by low creatinine.
There may be other reasons for creatinine decrease, it is recommended that patients go to regular hospitals in a timely manner, improve the examination to clarify the cause of the disease, and then give targeted treatment or therapy under the guidance of doctors.
